[0001] The present application relates to the technical field of air conditioners, in particular to a wind sweeping structure and an air conditioner. BACKGROUND

[0002] The wind sweeping blades of a vertical air conditioner usually only have a left and right wind sweeping function, and the left and right wind sweeping function is realized by left and right swinging of the wind sweeping blades. The vertical air conditioner in the prior art does not have an up and down wind sweeping function, and cannot bring better experience to users.

[0003] Therefore, the present application provides a wind sweeping structure and an air conditioner to solve the above technical problems. SUMMARY

[0004] The present application solves the technical problem that the prior art does not have an up and down wind sweeping function.

[0005] To solve the above problems, the present application provides a wind sweeping structure, comprising: a shell; a plurality of wind sweeping blades arranged side by side, the wind sweeping blades being movably connected to the shell, and the wind sweeping blades being capable of swinging left and right relative to the shell; and a driving structure capable of driving the plurality of wind sweeping blades to swing left and right; the wind sweeping blades further comprise: a plurality of baffles arranged along an up and down direction, and the baffles being obliquely arranged; when the driving structure drives the wind sweeping blades to rotate, the baffles change the up and down air outlet direction.

[0006] Compared with the prior art, the present application has the following technical effects: the plurality of wind sweeping blades are capable of swinging left and right relative to the shell, and the driving structure is capable of driving the plurality of wind sweeping blades to swing left and right; the plurality of baffles are arranged along the up and down direction, and the baffles are obliquely arranged; since the oblique angle of the baffles is fixed, when the wind sweeping blades rotate left and right, the baffles rotate by a certain angle with the wind sweeping blades to change the air outlet direction of the baffles, and the up and down wind sweeping function is realized by left and right rotation of the wind sweeping blades.

[0007] In the present embodiment, the wind sweeping blades further comprise: a frame, the frame being hollow in a front and back direction; and the baffles being installed on the inner side wall of the frame at a fixed oblique angle.

[0008] The technical effects of the present application are as follows: the front and back direction of the frame is hollow to serve as the overall frame of the wind sweeping blades, and the baffles are installed on the inner side wall of the frame at a fixed oblique angle to make the baffles in the frame present an oblique angle, thereby realizing up and down air blowing.

[0009] In the present embodiment, in an initial state, the baffles present a fixed angle of upward inclination; when the wind sweeping blades rotate by a first angle along the left and right directions, the baffles present a fixed angle of downward inclination.

[0010] The technical effect after the technical scheme is applied is that since the whole sweeping blade rotates around the rotating shaft, and the center line of the baffle is on the rotating shaft, when the baffle rotates with the rotating shaft, the baffle can be inclined upward or downward according to the rotating angle of the rotating shaft.

[0011] In the embodiment, the driving structure comprises a gear box shell, a gear set is arranged in the gear box shell, the gear set comprises a plurality of first gears, a plurality of transmission gears, each transmission gear is engaged between two first gears, a motor, an output shaft of the motor is connected with one of the first gears, and a plurality of sweeping blades are connected with the first gears one by one.

[0012] The technical effect after the technical scheme is applied is that the driving structure comprises the gear set, one of the first gears in the gear set is driven to rotate by the motor, the first gear is coaxially connected with the sweeping blade, the rotation of the first gear drives the sweeping blade to rotate, the transmission gears are engaged between the adjacent two first gears to ensure that the rotating directions of all the first gears are consistent, and the corresponding first gears correspond to the sweeping blades, so that the sweeping blades are synchronously rotated.

[0013] In the embodiment, the transmission gears and the first gears are consistent in size, so that when the motor drives the first gear to rotate, the transmission gears and the first gears are engaged to make the sweeping blades swing left and right at the same angle.

[0014] The technical effect after the technical scheme is applied is that in order to ensure that the sweeping blades rotate at the same angle, the transmission gears and the first gears are consistent in size, so that the transmission ratio of the transmission gears and the first gears is ensured, and the left and right swinging of the air conditioner is utilized.

[0015] In the embodiment, the limiting structure for limiting the left and right rotating angles of the sweeping blades comprises a first clamping part fixedly connected in the gear box shell and a second clamping part arranged on the transmission gear or the first gear, when the driving structure drives the sweeping blades to rotate left and right and the rotating angle exceeds a preset rotating angle range, the second clamping part abuts against the first clamping part to limit the driving structure from driving the sweeping blades to rotate.

[0016] The technical effect after the technical scheme is adopted is that the maximum angle range of the left and right swinging of the air-sweeping blade driven by the driving structure is limited by the cooperation between the first clamping part and the second clamping part. When the rotating angle of the air-sweeping blade is about to exceed the preset rotating angle, the first clamping part and the second clamping part are in contact to limit the continuous operation of the driving structure, thereby limiting the rotation of the air-sweeping blade. In this way, the phenomenon that the air-sweeping blade swings excessively to the left and right when the sensor fails when the motor controls the preset angle is avoided.

[0017] In the embodiment, the second clamping part protrudes along the circular surface of the first gear or the transmission gear, and the first clamping part protrudes along the inner side of the top wall of the gear box shell. When the left and right rotating angles of the air-sweeping blade are about to exceed the preset range, the first clamping part and the second clamping part cooperate to limit the left and right rotating angles of the air-sweeping blade.

[0018] The technical effect after the technical scheme is adopted is that by setting the second clamping part protruding from the end surface, when the first gear or the transmission gear rotates to a certain preset angle, the first clamping part and the second clamping part are in contact, thereby limiting the continuous rotation of the first gear or the transmission gear, and ultimately limiting the left and right rotating angles of the air-sweeping blade.

[0019] In the embodiment, the first clamping part includes a first limiting rib and a second limiting rib protruding along the inner side of the top wall of the gear box shell. In the initial state, the second clamping part is in contact with the first limiting rib, and when the air-sweeping blade is at the maximum rotating angle, the second clamping part is in contact with the second limiting rib. The first limiting rib and the second limiting rib are connected by an arc.

[0020] The technical effect after the technical scheme is adopted is that the first clamping part is more specific, that is, the first limiting rib and the second limiting rib are used. According to the setting position of the first limiting rib and the second limiting rib, the rotating angle of the second clamping part can be limited to achieve the limiting effect.

[0021] In the embodiment, the air-sweeping blade further includes a rotating sleeve arranged at one end of the frame body close to the gear box shell. The rotating sleeve cooperates with the transmission shaft on which the first gear is arranged to drive the frame body to rotate left and right.

[0022] The technical effect after the technical scheme is adopted is that in order to ensure that the rotation of the first gear can stably drive the air-sweeping blade to rotate, the air-sweeping blade in the prior art is improved. The air-sweeping blade body is a frame body, and the air outlet direction adopts a hollow design, in which a plurality of baffles are arranged. A rotating sleeve is arranged at one end of the frame body close to the gear box, and a hole is arranged in the rotating sleeve for inserting the transmission shaft.

Detailed Implementation

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] This invention provides a sweeping structure, such as Figures 1-7 As shown, it includes: a housing 100; a plurality of parallel-arranged sweeping blades 110, the sweeping blades 110 being movably connected to the housing 100 and capable of swinging left and right relative to the housing 100; a drive structure 120, the drive structure 120 being capable of driving the plurality of sweeping blades 110 to swing left and right; the sweeping blades 110 further include: a plurality of baffles 500, the plurality of baffles 500 being arranged along the vertical direction and the baffles 500 being inclined; when the drive structure 120 drives the sweeping blades 110 to rotate, the vertical air outlet direction is changed under the action of the baffles 500.

[0034] Wherein, the shell 100 is the shell 100 of the prior art floor type air conditioner, such as Figure 1 , the air sweeping blades 110 are movably connected on the shell 100 from left to right, so that the air sweeping blades 110 can swing left and right relative to the shell 100, and the distance between adjacent air sweeping blades 110 remains the same, so as to ensure that when the air sweeping blades 110 swing left and right to sweep air, the effect of uniform air outlet is achieved.

[0035] The driving structure 120 can drive the air sweeping blades 110 to swing left and right relative to the shell 100 simultaneously. The driving structure 120 can adopt a motor 800 to drive a gear and rack structure, and a gear is arranged on the shaft of each air sweeping blade 110, so that the motor 800 drives multiple gears to rotate synchronously to achieve the purpose of simultaneous rotation of multiple air sweeping blades 110, or a gear set is adopted, the gear set is provided with a transmission gear 310 and a first gear 300, the first gear 300 is coaxially arranged on the air sweeping blade 110, and the transmission gear 310 is arranged between adjacent two first gears 300 to achieve the effect of transmission.

[0036] As shown in Figures 3-6 , the air sweeping blade 110 adopts a frame body 610. In order to keep the air outlet direction reasonable and have a certain amount of air flow out, the frame body 610 is designed with a hollow structure. The frame body 610 is arranged with multiple baffles 500 along the first direction. The length of each baffle 500 can be the same or different. The same length of the baffle 500 can keep the air volume consistent, while the different length of the baffle 500 can be set according to actual needs, such as needing a larger air volume in the middle, the length of the baffle 500 can be set smaller to increase the air volume; such as needing a smaller air volume at the bottom, the length of the baffle 500 can be set longer.

[0037] Further optimization, the air sweeping blade 110 further comprises: a frame body 610, the frame body 610 is hollowly arranged in the front and back directions; the baffle 500 is fixedly installed on the inner side wall of the frame body 610 at a fixed inclination angle.

[0038] The baffle 500 is arranged at a fixed inclination angle, such as 30° or 45°, relative to the inner side wall of the air sweeping blade 110, so that the air outlet direction of the baffle 500 remains consistent under the premise that the air sweeping blade 110 does not rotate left and right. When the air sweeping blade 110 rotates left and right, the air outlet direction of the baffle 500 will rotate with the air sweeping blade around the axis direction. For details, please refer to Figure 4 、 5 、6.

[0039] Further optimization, in the initial state, the baffle 500 is inclined upward at a fixed angle; when the air sweeping blade 110 rotates by a first angle along the left and right directions, the baffle 500 is inclined downward at a fixed angle.

[0040] In order to make the upward or downward air outlet angle of the baffle related to the left and right rotating angle of the air sweeping blade, and adapt to different air conditioning modes. When the air conditioner is in cooling mode, as shown in Figure 4 , the left air outlet state of the air conditioner in cooling mode; as shown in Figure 5 , the right air outlet state of the air conditioner in cooling mode, since the baffle 500 is fixedly arranged on the inner side wall of the air sweeping blade 110, the air outlet direction is upward, at this time, the first gear 300 is rotated by 90° from the left air outlet state in cooling mode to the right air outlet state in cooling mode.

[0041] When the air conditioner is in heating mode, as shown in Figure 6 , the right air outlet state of the air conditioner in heating mode, since the baffle 500 is fixedly arranged on the inner side wall of the air sweeping blade 110, the air outlet direction is downward, at this time, the first gear 300 is rotated by 180° from the right air outlet state in cooling mode to the left air outlet state in heating mode. Figure 5 Position: the right air outlet position in cooling mode is rotated by 180° to obtain, that is, the right air outlet position in cooling mode and the left air outlet position in heating mode, since the air sweeping blade 110 is rotated by 180° relative to the rotating shaft, that is, the first gear 300 is rotated by 180°, and the baffle 500 in the air sweeping blade 110 is also rotated from the upward air outlet state to the downward air outlet state.

[0042] Further optimization, the driving structure 120 comprises: a gear box shell comprising a gear set therein, the gear set comprising a plurality of first gears 300, a plurality of transmission gears 310, each transmission gear 310 being engaged between two first gears 300; a motor 800, an output shaft of the motor 800 being connected to one of the first gears 300; a plurality of air sweeping blades 110 being correspondingly connected to the plurality of first gears 300. The driving structure 120 is preferably a gear box shell, as shown in Figure 1 , arranged on the upper surface of the shell 100, the motor 800 is a forward and reverse motor 800, which drives the air sweeping blade 110 to rotate in the positive direction by forward rotation, and drives the air sweeping blade 110 to rotate in the reverse direction by reverse rotation, and in order to ensure that a single motor 800 can control multiple air sweeping blades 110, thereby driving multiple air sweeping blades 110 to rotate simultaneously, transmission gears 310 are used for meshing transmission between adjacent first gears 300, so that the rotating directions of the plurality of first gears 300 are consistent.

[0043] Further optimization, the transmission gears 310 and the first gears 300 are the same size, which ensures that when the motor 800 drives the first gear 300 to rotate, the meshing effect of the transmission gears 310 and the first gears 300 makes the left and right swinging angles of the plurality of air sweeping blades 110 consistent.

[0044] Since the sizes of the plurality of sweeping blades 110 are consistent, to ensure that the swinging angles of the sweeping blades 110 are consistent, the sizes of the transmission gear 310 and the first gear 300 need to be kept consistent, so that the swinging angles of the plurality of sweeping blades 110 can be kept consistent.

[0045] Further optimization also includes a limiting structure for limiting the swinging angle of the sweeping blades 110, the limiting structure comprising: a first clamping member 200 fixedly connected in the gear box shell; and a second clamping member 210 arranged on the transmission gear 310 or the first gear 300; when the driving structure 120 drives the sweeping blades 110 to swing to an angle that will exceed a preset swinging angle range, the second clamping member 210 abuts against the first clamping member 200, so as to limit the driving structure 120 from continuously driving the sweeping blades 110 to swing.

[0046] As shown in Figure 2 the second clamping member 210 is fixedly installed on the surface of the leftmost first gear 300 and protrudes along the surface of the first gear 300, and the second clamping member 210 is preferably a protrusion, which functions as a clamping member; the inner side of the top wall of the gear box shell is provided with the first clamping member 200, which is also a protrusion, and the contact between the protrusions achieves the purpose of limiting the swinging angle of the sweeping blades 110; in order to enable the second clamping member 210 to contact the first clamping member 200 along the rotation track of the first gear 300 when the first gear 300 rotates, the first clamping member 200 is arranged at a position after the first gear 300 rotates a predetermined angle, for example, when the predetermined angle is 270°, an initial angle between the first clamping member 200 and the second clamping member 210 is 270°.

[0047] The first clamping member 200 and the second clamping member 210 are fixedly installed on the gear and the inner wall of the gear box, respectively; since the first clamping member 200 on the inner wall of the gear box is fixedly arranged, and the second clamping member 210 on the gear rotates along with the gear, when the gear rotates to a certain angle, the first clamping member 200 cooperates with the second clamping member 210 to limit the rotation of the gear, thereby limiting the rotation of the sweeping blades 110. In this way, the mechanical structure can limit the rotation of the gear to be within a preset rotation range, and the over-rotation of the gear does not occur.

[0048] Further optimization, the second clamping member 210 protrudes along the circular surface of the first gear 300 or the transmission gear 310, and the first clamping member 200 protrudes along the inner side of the top wall of the gear box shell; when the sweeping blades 110 swing to an angle that will exceed a preset range, the first clamping member 200 cooperates with the second clamping member 210 to limit the swinging angle of the sweeping blades 110.

[0049] The baffle 500 is set at a fixed tilt angle, such as 30° or 45°, relative to the inner wall of the sweeping blade 110, so that the air outlet direction of the baffle 500 remains consistent without the sweeping blade 110 rotating.

[0050] Further optimization includes the first engaging component 200 comprising a first limiting rib 410 and a second limiting rib 420 protruding along the inner side of the top wall of the gearbox housing; in the initial state, the second engaging component 210 is in contact with the first limiting rib 410, and when the sweeping blade 110 is at its maximum rotation angle, the second engaging component 210 is in contact with the second limiting rib 420; there is a rounded transition between the first limiting rib 410 and the second limiting rib 420.

[0051] like Figure 2 The gear cover plate 900 in the gearbox has five grooves 700 for mounting the shaft of the transmission gear 310 or the first gear 300. In the leftmost groove 700, there is a first limiting rib 410 and a second limiting rib 420. To ensure that the rotation angle of the sweeping blade 110 is limited to 280°, the angle between the first limiting rib 410 and the second limiting rib 420 is K. For example, when angle K is 80°, the maximum rotation angle (360-K) is 280°. Therefore, in the position shown in Figure 7, the second engaging member 210 is engaged with the first limiting rib 410, and when the sweeping blade 110 is at its maximum rotation angle, the second engaging member 210 is engaged with the second limiting rib 420. Meanwhile, in order to ensure that the first locking member 200 and the second locking member 210 can cooperate with the first limiting rib 410 and the second limiting rib 420, the first limiting rib 410 is arranged along the axial direction of the groove 700, and the radius of the arc transition between the first limiting rib 410 and the second limiting rib 420 is smaller than the radius of the groove 700.

[0052] Further optimization includes: a rotating sleeve 620 located at one end of the frame 610 near the gearbox housing; the rotating sleeve 620 cooperates with the transmission shaft where the first gear 300 is located, so that the first gear 300 drives the frame 610 to rotate left and right.

[0053] Accordingly, in order to ensure that the frame 610 can rotate relative to the housing, a rotating sleeve 620 is provided at the upper end of the frame 610. The rotating sleeve 620 cooperates with the transmission shaft. The rotating sleeve 620 and the transmission shaft can be connected by splines or flat keys to achieve stable transmission.

[0054] The present invention also provides an air conditioner, including: the above-mentioned air-sweeping structure, wherein the outer shell 100 has a groove 700, the groove 700 is located in the middle of the outer shell 100, and the groove 700 is used as an accommodating space for installing the above-mentioned air-sweeping structure.

[0055] Although the present application has been disclosed with reference to the above examples, it is not intended to limit the present application. Any person skilled in the art, without departing from the spirit and scope of the present application, can make various changes and modifications, and the scope of protection of the present application should be limited by the scope defined in the claims.
